Abstract

A wireless mobile device, either a WLAN enabled mobile device or a Bluetooth enable device, which is within range of a WLAN access point, is operable to receive GNSS assistance data broadcasted from the WLAN access point. The GNSS assistance data are acquired by the WLAN access point from a reference database coupled to a location server. The broadcast GNSS assistance data comprise ephemeris data, LTO data, location information related to the WLAN access point and/or time information. The WLAN access point receives the acquired GNSS assistance data from the location server over a broadband IP network. The WLAN access point selects available resources for broadcasting the received GNSS assistance data to wireless mobile devices in range. The wireless mobile device receives the broadcast GNSS assistance data to calculate its own location. The calculated location of the wireless mobile device is used to update or refine the reference database.
